USER’S GUIDE
HSF-325 OPERATION NOTICES
1. To prevent damage to the machine, toolholders, and cutting tools, please
read this User’s Guide carefully. This machine uses induction heating, and
the
temperature
of the toolholder being heated
will rise rapidly
according to
the heating time! Please confirm the characteristics of your toolholders and
cutting tools (material, external diameter, tolerances, etc.) to set accurate
heating cycles, in order to prevent damage to your toolholders, and extend
the life of the machine.
2. Stainless toolholders can easily damage the induction heating head. Stainless
toolholders may still be used in this machine; however, due to their lower
heating efficiency, they require more heat, which can cause the induction
head to overheat during repeated operation. The heating process should be
monitored closely. If the heating head gets overheated, please stop operation
temporarily until the heating head has cooled. Continuing operation while the
head is overheated
will damage the induction heating head
.
3.
DO NOT
use high-speed steel (HSS) cutting tools in induction heating
operations. Due to the similar heating characteristics between the tool and
the toolholder, it can be difficult or impossible to remove HSS cutting tools
from steel toolholders.
4. It is very important to know the diametrical size of your toolholders and
cutting tools. The machine is designed to heat toolholders to a sufficient
temperature to allow the cutting tools to shrink in/out (around 300°C). If the
temperature exceeds 350°C and the cutting tool still cannot be shrunk in/out
of the toolholder, it is likely an issue with the toolholder geometry, or the grind
tolerance of the cutting tool.
4.1. If the fit between the toolholder and cutting tool is too tight, it will be
difficult
to shrink out
the cutting tool. If the fit between the toolholder and cutting tool
is too loose, the tool is more likely
to pull out of the holder
during cutting
operations. Please choose cutting tools with the appropriate precision.
